in its holder. Fig. 11 is pa t p an and part 5 horizontal section of the same; in which I is the ring, 3 is the ring holder, 1 is a groove in the holder with an oiled wick placed therein, ii is'an open ring of metal wire, 9 is a groove on the interior of the holder, I0 is a groove on the exterior of the ring and I i is the opening-between the ends of the ring 8.

The feature of my invention consists in leaving the ring free to rotate within its holder but preventing the ringfrom being lifted by yarn tension,

-the object being to ease oil the effect on travellers caused by uneven tension stresses of yarn being As shown by the drawing, the ring has a groove It on its exterior and the holder a corresponding groove 9 on its interior. In the latter groove there is placed a ring 8 ofmetal wire open in one part, as at I i and the ring I snapped in is torotatewithintheholder 3. a 4

In the groove I there is provided an oil wick which is in contact lightly with the bottom face "ofthe ring, which acts as a brake on the; ring in casethe ring is caused to rotate ioo freely. Having thus described my invention what I claim is:

l.,-=A device of the a ring holder, a in said holder, said ring and said holder having cooperating grooves in opposed faces, and an open-ended metallic ring'positioned in the space deflned by said grooves and preventing the spinnin'g ring from being lifted out of the holder.

class described, comprising 2. A device of theclass described, comprising a l'lnghlblder, a spinning ring rotatably mounted in said holder, said ring and holder cooperating grooves in opposed faces, and an openended metallic spring ring carried by the spinning ring and positioned in the groove formed therein, said spring ring extending beneath the a vertical cross section of the ringplaced to provide horizontal netallic spring ring thereby held from reing lifted but remains free spinning ring rotatably mounted upper edge defining the groove in the rin holder and thereby preventing the spinning ring from being lifted out of the holder. L 3. A device of the,class described, comprising a ring holder internally shouldered at its upper end to provide horizontal and vertical faces, a spinning ring seated on said horizontal face and having a vertical face opposite the vertical face of the holder, said vertical'faceshaving grooves therein opposite one another, and an open-ended metallic spring ring positioned in the space defined by said grooves, said spring rlngprevente ing the spinning ring from being lifted out of the 4. Ade'vice of the class described, comprising a 15 ring holder internally shouldered at its upper end 7 and vertical faces, a spinring seated on said horizontal face and i having a vertical face opposite the-vertical face of the holder, said vertical faces having grooves go therein opposite one another, an open-ended positioned in the space defined by said grooves. said spring ring preventing the spinningeri'ng from beinghlifted out of the holder, the horizontal face of said holder on which u the spinning ring seats being grooved, and an oil wick positioned in and substantially filling said groove.

5. A device of the class described, comprising Y a ring holder'internally shouldered at its upper so and to provide horizontal and vertical faces, a. spinning ring seated on said horizontal face and having a vertical face opposite the vertical face of the holder, said vertical faces having grooves therein opposite one-another, and an'open-ended metallic spring rin carried by the spinningring 5 and positioned in the grooveformed in its verti-,

cal face, the upper edge definingthe groove. in

the vertical face of the ring holder vertically overwhereby said spring ring 40 ring from being lifted out lying the spring ring, prevents the spinning of the holder. .7
